DNA Mutation

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

Where do mutations occur?

• DNA and RNA
• DNA 
• RNA
• mRNA and tRNA

In an insertion mutation

• One base is added to the DNA sequence, codons stay the same

• One base is eliminated, codons stay the same

• One base is added to the DNA, Codons are different

• One base is replaced, codons are different
